Roofing shingle



Dec. 26, 1939. R. SPAIN ROOFING SHINGLE fiM TTORNEY INVENTOR 12.1,. fipazn/ BY M 4 Filed April 27, 1939 Patented Dec. 26, 1939 UNITED STATES PATENT OFFICE 7 Claims.

My invention relates to shingles and more particularly contemplates the provision of a shingle of the interlocking type in which tongues and slots are provided for holding the shingles in position. i

My invention further contemplates the provision of a shingle which may readily be cut from rolls of flexible roofing material and then stacked in boxes for shipping to the point of use.

My invention further contemplates the provision of shingles formed with tongues for interlocking engagement with adjacent shingles to prevent curling or leakage when applied on a roof.

My invention embodies other novel features, details of construction and arrangement of parts which are hereinafter set forth in the specification and claims and illustrated in the accompanying drawing, forming part thereof, wherein:

Fig. l is a plan view showing several of my improved shingles in assembled relation;

Fig. 2 is a sectional view taken along the line II-II of Fig. 1, showing the manner in which the shingles are interlocked to prevent curling or leakage;

Fig. 3 is a plan View showing a shingle as it appears in blank form prior to bending the tabs thereon; and

Fig. 4 is a plan view of a shingle after the tabs have been bent into position for interlocking engagement.

Referring now to the drawing for a better understanding of my invention, I show a shingle 6 in the form of an irregular octagon having four long sides I and four short sides 8. As shown in Fig. 3, the shingle is cut through by spaced parallel slits 9 extending in a vertical plane and having their upper ends connected by a transverse slit ll, said slits being arranged in the form of an inverted U-shape to form a tab E2. The shingle is creased to form a bend line I3 extending parallel to the slit H and disposed at the base of the tab l2.

A tongue I4 is formed on the far side of the shingle from the tab I2 and in vertical alignment therewith. The tongue projects beyond its adjacent short side 8; and the shingle may be cut through with slits l6 which extend in alignment with the sides of the tongue to thereby lengthen same, if desired. The shingle is creased at the base of the tongue to form a bend line ll.

Prior to laying the shingle, its upper end portion 18 is bent upwardly and back, about the bend line l3, to aposition above the top of the shingle; and the tongue [4 is bent under the shingle,

In laying the shingles, the upper shingle tongue I4 is positioned under the retainer flap formed by the portion IS on the lower adjacent shingle; and the shingles are spaced laterally by aligning their short side edges 8,with the sides of the underlying shingle tabs l2. Nails I9 are driven through the sides of the shingles and thence through the retainer fiap portions it of the underlying shingles. When the fiap portions l8 arenailed down they tightly engagetheunderlying tongues M to prevent curling of the shingles or the leakage of rain thereunder. It will be observed that all nail heads are covered by overlying shingles.

While I have shown my invention in but one form it is obvious to those skilled in the art that it is not so limited but is susceptible of various changes and modifications without departing from the spirit thereof; and I desire, therefore,

that only such limitations shall be placed there- 2 upon as are imposed by the prior art.

I claim:

1. A roofing shingle having its upper portion slit and bent back thereover to receive and hold the lower portion of an overlying shingle in position in the slit.

2. A roofing shingle having a tongue formed on its lower portion, and said shingle having its upper portion slit and bent back thereover to receive and hold the tongue of an overlying shingle.

3. A roofing shingle having a tongue bent thereunder from its lower portion, and said shingle having its upper portion slit and bent back thereover to receive and hold the tongue of an overlying shingle.

4. A roofing shingle having a tongue formed on its lower portion and bent thereunder, and said shingle having its upper portion slit to form a projecting tab when the upper portion is bent back thereover to receive and hold the tongue of an overlying shingle in the slit and under the bent-back upper portion.

5. A shingle according to claim 4 in which, the projecting tab serves as a spacing and aligning means for adjacent overlying shingles.

6. A shingle according to claim 4 in which, said shingle is in the form of an irregular octagon having four short sides and four long sides.

'7. A shingle according to claim 4 in which, said shingle is in the form of an irregular octagon having four short sides and four long sides, and said tongue and projecting tab are formed on diametrically opposed short sides.
